are many outcrops of qiiartzite in Westmoreland, the most extensive is 

 south-east of Granger's mill and just east of a road now practically dis- 

 continued. The strata dip nearly north-west, generally about 15°; and, 

 what is rather uncommon, we have in it great veins of quartz. On the 

 south-east there is a narrow band of wrinkled argillaceous schist ; and on 

 the north-west a similar rock that extends to Westmoreland depot. This 

 wrinkled schist probably entirely surrounds the quartzite, and rests on its 

 edges. Just above Granger's mill, in the stream, we have the mica schist 

 with staurolite, that is the jDrevailing schist of Unity and Acworth. Here, 

 with strata nearly horizontal, it lies on the quartzite. The rock that out- 

 crops on the road near Westmoreland village seems rather to belong to 

 some of the lower formations, though it has in its jointing and cleavage 

 some resemblances to the Coos quartzite. On the road now discontin- 

 ued, that runs east from the Hill Village, we find quartzite dipping di- 

 rectly north. Near Wm. Starkey's the quartz schist probably belongs to 

 the quartzite band, and, with varying texture, extends south-west to the 

 town line. A rock that resembles it very closely is found at the molyb- 

 denite mine; but a typical variety of the quartzite is found south-west 

 of the mine near T. Dunham's, in the corner of Chesterfield. South- 

 east of Dunham's, near T. Briggs's, we have a band of whitish quartz 

 schist, which resembles that at Starkey's. 



South-east of Factoryville in Chesterfield, perhaps a hundred rods from 

 the church, there is a marked outcrop of quartzite. While most of the 

 rock is like ordinary quartzite, where the rounded grains appear to be 

 imbedded in a purely siliceous, glossy-looking cement, there are masses 

 of the rock here in which the cementing material is almost altogether 

 wanting, and the rock is really a white, friable sandstone. A few dark- 

 shaded lines running through it give to the rock the appearance of lime- 

 stone ; and it was thought to be marble by the country people who had 

 seen it. At school No. 12, south of Spofford lake, a narrow band of 

 quartzite extends southward nearly a fourth of a mile. West of the lake, 

 on the hill north of William Bennett's, the quartzite appears, and proba- 

 bly extends southward, as it crosses the road half a mile west of the 

 Lake house ; and on the road from the lake to Chesterfield it can be seen 

 on the west of the road. In the south-west part of the town, near a saw- 

 mill, we have probably the extension northward of the quartzite so exten-
